Abstract
The utility model discloses a kind of wheelchair brake device, it includes braking brake disk, bolt rod, bracing wire and pedal.Braking brake disk is fixed in axis of wheel rotation, and as wheel is rotated together；On braking brake disk the through hole that bolt rod is penetrated/passed is supplied provided with several；Bolt rod is fixed on Wheelchair support, is not rotated with the rotation of wheel；One end of bracing wire is worn after spring to be connected with bolt rod, and the other end of bracing wire is connected with pedal.When needing to fix wheelchair, pedal release bracing wire is slammed, under the reaction of spring, bolt rod is promoted, inserts it into the through hole of braking brake disk, braking brake disk is locked, and then wheel is pinned, wheelchair is not moved, meanwhile, pedal is pinned certainly.When needing to promote wheelchair movement, pedal is slammed, bracing wire pull-up bolt rod makes bolt rod be extracted from the through hole of braking brake disk, meanwhile, pedal self-locking, wheelchair can freely walk.
Description
Technical field
The utility model is related to a kind of brake gear, specifically, is related to a kind of brake gear on wheelchair.
Background technology
At present, most wheelchairs are braked using friction mode, i.e. hand-operated brake rod, made it with tire friction eceleration, are stopped
Car.This mode is easy to be influenceed by the extraneous factor such as tire pressure or operation strength size, causes wheelchair brake dangerous, can not
Lean on.
The content of the invention
In view of the foregoing, the purpose of this utility model is to provide a kind of new wheelchair brake device, the brake gear
It is simple in construction, it is easy to operate, reliably and securely wheelchair brake can be lived.
To achieve the above object, the utility model uses following technical scheme：A kind of wheelchair brake device, it includes brake
Brake disc, bolt rod, bracing wire and pedal；
Braking brake disk is fixed in axis of wheel rotation, and as wheel is rotated together；If being provided with braking brake disk
The dry through hole for penetrating/passing for bolt rod；
Bolt rod is fixed on Wheelchair support, is not rotated with the rotation of wheel；
One end of bracing wire is connected by extension spring with bolt rod, and the other end of bracing wire is connected with pedal.
In preferred embodiment of the present utility model, the two ends of the pedal are respectively equipped with spring pearl, correspondingly, in pin
Pedal base two ends are provided with the circular hole for self-locking.
In preferred embodiment of the present utility model, the utility model also includes a bolt rod support, and the bolt rod leads to
Cross the bolt rod support to be fixed on Wheelchair support, the extension spring is arranged in the cavity of the bolt rod support.
The utility model also includes an opening sleeve, and the opening sleeve is fixed on axis of wheel rotation；The braking brake disk passes through
Pin is fixed on the opening sleeve.
The utility model is simple in construction, easy to operate, practical.It utilize latch principle, need wheel chair wheel is locked
When motionless, pedal is slammed, bracing wire is discharged, in the presence of extension spring, bolt rod is promoted, inserts it into the through hole of braking brake disk
It is interior, wheel is locked together with Wheelchair support, wheelchair is prevented when unattended, or voluntarily moved on wet and slippery or tilted road surface
It is dynamic, cause to take people and the unnecessary injury of other staff.When needing to move wheelchair, pedal is slammed, bracing wire is pulled, passes through
Bracing wire extracts bolt rod from the through hole of braking brake disk, while pedal self-locking, holding latch bar state is constant, wheel can
Freely to rotate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, wheel-chair brake gear disclosed in the utility model includes braking brake disk 1, bolt rod
2nd, bracing wire 3 and pedal 4.
Braking brake disk 1 is fixed in axis of wheel rotation 5, and as wheel is rotated together.It is provided with braking brake disk 1
Several supply the through hole 6 that bolt rod 2 is penetrated/passed.
Bolt rod 2 is fixed on Wheelchair support 8 by bolt rod support 7, is not rotated with the rotation of wheel.
The intracavitary of bolt rod support 7 is provided with an extension spring 9, one end of bracing wire 3 is drawn by being connected after extension spring 9 with bolt rod 2
The other end of line 3 is connected with pedal 4.
The two ends of pedal 4 are respectively equipped with spring pearl 10, correspondingly, and the circle for self-locking is provided with pedal base two ends
Hole 11.
As shown in Fig. 2 when needing to promote wheelchair movement, slamming the top of pedal 4, the pull-up bolt rod 2 of bracing wire 3 makes
Bolt rod 2 is extracted from the through hole 6 of braking brake disk 1, meanwhile, pedal 4 by the cooperation of spring pearl 10 and circular hole 11 from
Lock, wheelchair can freely walk.
When needing to fix wheelchair, the bottom of pedal 4 is slammed, bracing wire 4 is discharged, in the presence of extension spring 9, latch is promoted
Bar 2, is inserted it into the through hole 6 of braking brake disk 1, and braking brake disk 1 is locked, and then pins wheel, wheelchair is not moved
It is dynamic, meanwhile, pedal 4 is pinned certainly by the cooperation of spring pearl 10 and circular hole 11.
Braking brake disk 1 of the present utility model is set in axis of wheel rotation 5, naturally it is also possible to as shown in figure 1, by opening
Muzzle 12 is fixed in axis of wheel rotation 5.As illustrated, opening sleeve 12 is set in axis of wheel rotation 5, braking brake disk 1 leads to
Pin 13 is crossed to be fixed on opening sleeve 12.
In order to manipulate conveniently, pedal 4 may be mounted at wheelchair side or the accessible place of user's pin.
The utility model is simple in construction, easy to operate, and it utilizes latch principle, when needed, by wheel and Wheelchair support
Lock together, prevent wheelchair when unattended, or the automatic moving on wet and slippery or tilted road surface, cause to take people and other people
The unnecessary injury of member.
